How to Use the Wall SQFT Calculator

To use this calculator, simply enter the width and height of the wall in feet. Then, if you have any windows or doors on the wall that need to be subtracted from the total paintable area, enter the number and dimensions of these openings.

Calculation Methodology

The calculator first computes the total wall area by multiplying the width and height. It then calculates the total area of the windows and doors by multiplying their individual dimensions and summing the results. Finally, it subtracts the area of the windows and doors from the total wall area to give you the paintable area.

Limitations

This calculator assumes all walls are perfectly rectangular and does not account for any irregular shapes or additional features. Please measure carefully to ensure accurate results.
